Difficulty in using switch-case

I want to display certain labels on the basis of the value supplied in switch .But it's not working . I don't know how to overcome the problem .Kindly guide me.
My page is as follows:
<html>
<head>
</head>
<body>
<%!
     int i=1;
%>
<%
     switch(i)
%>
<%
     case 1:
%>
In case 1.
<%
     break;
%>
<%
     case 2:
%>
In case 2.
<%
     break;
     default :
%>
</body>
</html>

The JSP interpreter is putting in statements which makes your code not compile.
This is caused by the carriage returns in your jsp code.
switch(i)
out.print(__constantTable.getString(103)); // *** Syntax: SwitchLabels expected after this token
case 1:
out.print(__constantTable.getString(165));
break;
out.print(__constantTable.getString(98)); // *** unreachable code
case 2:
out.print(__constantTable.getString(166));
break;
default :
}Solution
1 - Don't mix scriptlets and jsp code in this way. Particularly closing %> and then opening again.
The following will work
<%!
int i=1;
%>
<%
switch(i){
case 1:
%>
In case 1.
<%
break;
case 2:
%>
In case 2.
<%
break;
default :
%>2 - a better solution is to use a custom tag, or tag library like JSTL to implement this
<c:choose>
<c:when test="${i == 1}">In Case 1 </c:when>
<c:when test="${i==2}"> In Case 2 </c:when>
<c:otherwise> Default value </c:otherwise>
</c:choose>Cheers,

In this input file it is having multiple records. Based on the AvailQty, the input file should go to the webservice. If the condition AvailQty is !=0, the the input file should go to the java webservice or else it should go to the .net webservice. In BPM i have used switch step for this. if i give the input file structure like above it is going to the java webservice only. It is not entering to the esle part.
Could you please help me out in this issue.
Thanks & Regards,

Hi,
Having had a look at these blogs:
Illustration of Multi-Mapping and Message Split using BPM in SAP Exchange Infrastructure
How to Split Message through BPM in 1:n scenario
Transformation Step to Implement 1:n Splitting
I think the best solution for your scenario is the following:
In your BPM use a TransformationStep that does the multimapping N:1
And then send the messages individually. You don`t need a Switch Step.
You should have two Receiver determination.
1.- File_server --> Integration Process.
2.- Integration Process --> WebService.
In the second RD, add two receiver Services (e.g. JAVA_WebService and NET_WebService) and
use routing roules that checks if AvailQty is !=0. And depending on this condition,
the message should be sent either JAVA_WebService or NET_WebService.
Hope this helps you.

DoGet method is called 2 times when a switch-case statement is used

TIA!

in your case you want 'count' to be a class attribute rather than a local variable. But yes, incrementing it each time that the method is called will serve your purpose.

Troubles with a switch case and final expression?

Been developing C/C++ for quite a while and still new to Java, and struggling with even the simplest things ... Why isnt this switch/case working?
have some final "variable" declared in a class contating "constants" like this ...
public class CConstants {
public static final int MY_CONSTANT1 = 0x01;
}Now, If I'm trying to use "MY_CONSTANT1" in a case stateent, I get the error "constant expression required" ?
CConstants c = new CConstants();
switch(condition){
case c.MY_CONSTANT1: { //do some work; break; }
default: { }
}I thought this would be a nice idea to increase readability as there will be a long switch/case statement.
Please help!

Edited by: George.F on Sep 3, 2009 3:08 AM

You should refer to that constant as CConstants.MY_CONSTANT1.
Refering to it via a reference to CConstants is possible but strongly discouraged (infact I'd make CConstants non-instantiable by adding a private constructor).
Other than that your code should work.
Could you post a SSCCE that demonstrates your problem.

Switch/Case: How to test byte values in hex format

OK, this may be a silly question, but being new to Java, I can't seem to get this to work.
I have a byte value that I want to test in a switch/case statement. The value was assigned to the byte in hexadecimal format. However, testing only works if I use the decimal value of the byte!
What's even stranger: It does work in a simple if/else statement. In my debugging attempts, I discovered this using the following code:
//*temporary debug routine
memoryCells[0] = (byte) 0x86; //LDA
if(memoryCells[0] == (byte) 0x86)
    System.err.println("byte recognized as hexadecimal!");
else
    if(memoryCells[0] == -122)
        System.err.println("byte recognized as decimal!"); So, this works in an ordinary if/else statement, but why doesn't it also work in the complex switch/case statement? Snippet below:
       switch (currentOpcode)
            case (byte) 0x86:
                //*LDA immediate (2 bytes, 2 cycles)
                registerA = b;
                currentOpcode = 0x00;
                cycleCounter = 0;
            break;
        }Thanks in advance for any suggestions...

    public static void main(String[] args) throws Exception {
     byte test = (byte)0x86;
     switch(test)
     case (byte)0x86:
              System.out.println("Success");
          break;
     default:
              System.out.println("ooops");
    }This works for me.

Switch/case limit

I am encountering a very strange problem.. after 39 cases in
my switch case statement the 40th case does not get executed.. the
code is in my go button and there are like 1000+ lines of code in
there.. if I replace my 39th case with the 40th it works but it
doesn't execute anything after that!! is there a limit on the
number of case statements we can use in action script??? I am
really confused with this problem...

no, but there is a byte limit on a single code block ... I
can't remember the number off hand. So that's probably what's going
on there, you might want to consider a looping test or using an
array.

Help with Switch-Case Statement

How do you get this in a switch-case statement or work with it?
          if (age < 70) {

          else (age > 99 && age < 110) {
                    JOptionPane.showMessageDialog(null, "People that are in their 100s are called centenarian.");
               }Thanks~

As per Java Specification, swtich case expects an integer and boolean cannot be used as param for switch.
In your case switch can be used like this.
int index = age /10;
switch(index) {
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
Your First case
break;
case 7:
your second case
break;
case 8:
third case
break;
case 9:
fourth case
break;
default:
fifth case
break;
Take note of the break statements. Its very important. But I wont prefer in this case. Code looks awkward and is not so meaningful.....

Regular expression in a switch case

Hey guys,
I have a string "52x + 60" and i want to extract 52x and 60 using regular expressions and a switch case
Is this the right way of doing it?
var equation:String = "32x + 5"
var numberExract:RegExp = /\d+/
var xExtract:RegExp = /d+/x/
for(var i:Number=0; i<equation.length; i++)
                    switch(equation.charAt(i))
                              case numberExtract.exec(equation):
                              trace("number");
               break;
               case xExtract.exec(equation):
               trace("x");
               break;
Because it's not tracing anything when i try

Here is a quick and dirty approach - can be customized, optimized and more elegant expressions used:
// equation
var string:String = "x^2 + 5x + 5 - x7 + 8 / 4";
// value replacing xs
var value:Number = 60;
// replace xs with value
// if x comes after digit
string = string.replace(/(?<=\d)x/g, String("*" + value));
// if x comes before digit
string = string.replace(/x(?=\d)/g, String(value + "*"));
// all other xs
string = string.replace(/x/g, String(value));
// remove spaces
string = string.replace(/\s/g, "");
// get pairs with first level math
var pattern:RegExp = /(\d+[\*\^\/]\d+)|\D|\d+/g;
var result:Number = stringToMath(string.match(pattern));
trace("result", result);
function stringToMath(match:Array):Number
    // digits surrounding operator
    var pattern:RegExp = /\d+\D\d+/;
    for (var i:int = 0; i < match.length; i++)
        if (match[i].match(pattern))
            match[i] = String(calculate(match[i]));
    trace("loop result", match);
    return calculteSum(match);
* Calculates sums
* @param    array
* @return
function calculteSum(array:Array):Number
    var result:Number = array[0];
    for (var i:int = 1; i < array.length - 1; i++)
        if (array[i] == "+")
            result += array[i + 1];
        else if (array[i] == "-")
            result -= array[i + 1];
    return result;
* First level math
* @param    string
* @return
function calculate(string:String):Number
    var operator:RegExp = /[\+\*\/\^\-]/g;
    var digits:Array = string.match(/\d+/g);
    var num:Number = 0;
    if (digits && string.match(operator) && digits.length > 1)
        switch (string.match(operator)[0])
            case "*":
                num = digits[0] * digits[1];
                break;
            case "/":
                num = digits[0] / digits[1];
                break;
            case "+":
                num = digits[0] + digits[1];
                break;
            case "-":
                num = digits[0] - digits[1];
                break;
            case "^":
                num = Math.pow(digits[0], digits[1]);
                break;
    return num;

Multiple Column hiding in advance table using Switcher

Hi All,
I am having requirement of hiding multiple columns in advance table using swithers.
Lets says I am searching for the the parties in party search page. If the party is of type person then two columns should be visible one is firstName and LastName.
and If party is of type organization then firstName and lastName column shpould be hidden and only the PartyName column should be visible.
Is this possible through switchers if yes please explain?
Br, 903096

Hi ,
This can be done through switcher case , along with switcher you also need to use SPEL binding the each of those attribute
that you wish to hide .
Go through delete exercise to understand how to implement switchers case .
Let me know if you need any help .

OATS: trying to use switch statement.

Hi All,
I am trying to use the case statement in my functional script.
I am inserting the value in text-box lets say 1 , 2 , 3 ,4.
and have created the Databank as
Value in text-box               Name
1                                      A
2                                      B
3                                      C
i want that when i enter the value in text-box as 1 it should execute some code and if 2 then other code.
cases will be like
switch (??)
case A:
execute code1
case B:
execute code2
case C:
execute code3
My ques is how i can compare the values like :
if i enter the value 1 in text-box it should take case A, if if i ll enter 2 in text-box it should take case 2.
I am using this approach so that i can change the values 1 , 2 , 3 in the databank anytime i need and play the script.
can anyone please tell me how i can do so.
Thanks in advance.
Thanks
Ketan

Based on my understanding, textbox is an object in additional interface for script selection during playback
HashMap<String, String> selectScript = new HashMap<String, String>();
            for (int count = 0; count < getDatabank("DataBank Alias Name").getDatabankRecordCount(); count++) {
                getDatabank("DataBank Alias Name").getNextDatabankRecord();
                selectScript.put(eval("{{db.DataBank Alias Name.Value in text-box}}"), eval("{{db.DataBank Alias Name.Script Name}}"));
        Get the text entered in textbox and assign to a String, say key
info("Script selected is - " + selectScript.get(key));
getScript(selectScript.get(key)).run(1,true,true,true);

BPEL-Instanz dies silent if switch case is true boolean

Hello,
it is very curios. I have the following switch case:
xp20:compare('string1', 'string2') = 0
or
string(xp20:compare('string1', 'string2')) = '0'
The validation is ok, and the compiler compiles with 0 errors / 0 warnings.
If I try to invoke the process, the instance dies silent.
If i write 'string1' = 'string' the behavior is as expected and the instance is running.
What's the reason
I am using the last stable release version.
Best regards
Harald

i just tested your case in 10.1.3.x, it works fine for me. i can see "'two strings do not match" in output variable as expected. can you please copy and past your entire switch block.
here is my test case ( i took the Switch.bpel sample under references directory):
<switch>
<case condition="xp20:compare('string1', 'string2') = 0">
<assign>
<copy>
<from expression="'Value is greater than zero'"/>
<to variable="output" part="payload" query="/tns:resultMsg/tns:valueResult"/>
</copy>
</assign>
</case>
<otherwise>
<assign>
<copy>
<from expression="'two strings do not match'"/>
<to variable="output" part="payload" query="/tns:resultMsg/tns:valueResult"/>
</copy>
</assign>
</otherwise>

I want to divide this input file into two parts based on one condition. If the Availability!=0, then it should display the available quantity. or else, it should get suppliers from the webservice.
For this reqiurement, i have used the switch case. but it is not working. It is considering only the last record, For eg, in this input file the last record is having Availabilty=0. So it should go to webservice and display the suppliers. But all the 3 records are going to the else branch and giving the supplier details.
Could you please tell how to resolve the issue.the Availability which is present should go to one branch and the remaining records should go to the else branch. Please help me in this regard.

Hi, Leelaratnam:
What Anand mentioned is to split the message based on your node of "Details":
Each "Details" node will generate new message which only have one <Availability> elements (u will need another message type)
Then you can pass to your webservice, avoid your problem that only last <Availability> passed to webserivce.
You will have a multi-mapping (1:n)
in you BPM, you will have transformation step, then a block (ForEach) to process your splitted message one by one.
Yes, this is one solution.
Check my previous response, you will just need one mapping program, one transformation step, you can also achieve your purpose. However, in your mapping program, you need to code a UDF to do a lookup.

Switch case list UI

Hi!
For pedagocial and c-like reasons i'd like there to be a "Case-unbundle", which would be very nice if you're only calling sub-vi's in a case e.g.
Is there any way to create such a thing?
Instead of the Case-square i want it to be a "Unbundle by name" where i connect each output to my sub-vi's (like a multiplexer) and the appropriate one is called.
Any ideas?

Well, nice asumptions, but i have another one:
LabVIEW has a case structure where only one single case is visible at a time. This is a huge difference to C-based languages where a switch-case displayes every case at the same time in a "list".
I think the question from the OP is: "Is it possible to display a case-structure in LabVIEW 'flattened' so that every case is visible at the same time?"
And to answer this question: No it is currently not possible, was never possible and hopefully will never be. But you can create a "report" using the print-function and this can automatically create screenshots of each case and display them next to each other.....
just my 2cents
